Foreign Office updates Thailand travel advice following drought

Travellers to Thailand are being warned about the possible dangers of drinking tap water as the country heads for its worst drought in four decades.

A prolonged period without rain has led to some sea water entering the fresh water supply, which is affecting tap water, said the Foreign and Commonwealth Office.

"This issue may continue for several months," said the FCO. "Thailand's Metropolitan Waterworks Authority advise that there is no risk to public health from drinking tap water but salty water can affect people in higher risk groups, such as those with kidney disease.

"If you are concerned about the risks to your personal health, you should drink bottled water and/or get medical advice."

Some in Bangkok say they can taste salt in the water, a problem which is believed to have occurred because the city's Chao Phraya river has become too low to keep sea water out.
